Figure 3: Antimicrobial activity profile presented by strain 235 in SDS-PAGE. The gel strips containing 300-fold concentrated supernatant fluids were stained with Coomassie brilliant blue to reveal the secretory protein profile (a) or overlaid with semisolid LB agar containing the indicator strain (LF-4) to show the inhibition zones (b). For details see text. Numbers on the left indicate relative molecular mass markers (in kDa).
